ABSTRACT

OBJECTIVE: Previous research has demonstrated that individual risk of mental illness is associated with individual, co-resident, and household risk factors. However, modelling the overall effect of these risk factors presents several methodological challenges. In this study we apply a multilevel structural equation model (MSEM) to address some of these challenges and the impact of the different determinants when measuring mental health risk.

STUDY DESIGN AND SETTING: Two thousand, one hundred forty-three individuals aged 16 and over from 888 households were analysed based on the Household Survey for England-2014 dataset. We applied MSEM to simultaneously measure and identify psychiatric morbidity determinants while accounting for the dependency among individuals within the same household and the measurement errors.

RESULTS: Younger age, female gender, non-working status, headship of the household, having no close relationship with other people, having history of mental illness and obesity were all significant (p < 0.01) individual risk factors for psychiatric morbidity. A previous history of mental illness in the co-residents, living in a deprived household, and a lack of closeness in relationships among residents were also significant predictors. Model fit indices showed a very good model specification (CFI = 0.987, TLI = 0.980, RMSEA = 0.023, GFI = 0.992).

CONCLUSION: Measuring and addressing mental health determinants should consider not only an individual’s characteristics but also the co-residents and the households in which they live.

ABSTRACT

BACKGROUND: Pregnancy losses remain a neglected issue and it will be taking more than a century before a pregnant woman in Sub Sahara has the same chance of her baby being born alive as a woman in a high-income country. Pregnancy loss data are limited and not universal in Sub Saharan countries. This study was aimed to assess the magnitude and determinants of pregnancy loss in eastern Ethiopia.

METHODS: This study was conducted in, open continues and dynamic cohort of population, Kersa Health and Demographic Survillance site (HDSS) in Eastern Ethiopia in 2008-2019. All mothers who had known pregnancy outcomes during the period and reside in Kersa HDSS were considered. The prevalence proportions were calculated as the sum of all pregnancy loss divided by the number births in the specified year. Log-Binomial regression was used to determine factors associated with pregnancy loss. Prevalence Proportion Ratio (PPR) was used to report the magnitude and strength of association. A p-value of less than 0.05 was considered statistically significant.

RESULTS: From 39,153 included pregnancies, 810 (20.7; 95%CI:19.32, 22.15 per 1000 births) experienced pregnancy loss. Stillbirth was higher than abortion (11.14 Vs. 9.55 per 1000 births). Lacking own income (aPPR:1.26; 95%CI: 1.01, 1.58), being daily laborer (aPPR:1.44; 95%:1.08, 306) history of previous pregnancy loss (aPPR:2.26, 95%CI:1.69, 3.03), unwanted pregnancy (aPPR:1.26; 95%CI:1.01, 1.80), not receiving antenatal care (aPPR:1.59; 95%CI: 1.19, 2.13) and not receive the TT-vaccine during pregnancy (aPPR:1.33; 95%CI: 1.08, 1.80) were positively associated with pregnancy loss.

CONCLUSIONS: The overall rate pregnancy loss was ranged between 19.32, 22.15 per 1000 births with higher still births than miscarriage or abortion. Pregnancy loss was positively associated with social factors reproductive health factors, and maternal health service utilization.

ABSTRACT

BACKGROUND: Type 2 diabetes (T2D) and coronary artery disease (CAD) are chronic illnesses where adherence to a healthy lifestyle is crucial. If organisational and cultural factors are well managed, Peer support programs (PSP) can improve self-management, quality of life, and health outcomes. In preparation for launching a PSP, we surveyed family doctors (FD) about their attitudes toward such a program and about potential barriers, and facilitators.

METHODS: In March 2020 we surveyed 896 FDs from five university teaching practice networks in North-Rhine Westphalia, Germany, via an anonymous web-based survey. The questionnaire addressed details of PSPs, including suitable patients and FDs’role. Data were analysed using descriptive and inferential statistics; qualitative material underwent content analysis by two researchers.

RESULTS: A total of 165 FDs responded (response rate: 18.4%), 97% were practice owners. Respondents viewed PSPs positively (T2D: 92.0%, CAD 89.9%), especially for patients with poor self-structuring (82.7%), low motivation (76.3%) and few social contacts (67.6%). On average, FDs were able to identify 4.0 ± 3.2 patients as potential group leaders. Major facilitators reported included motivation by peers (92.5%), exercise (79.1%), and social contacts (70.1%). Waning interest over time (73.1%) and poor motivation (70.9%) were considered barriers. The majority of FDs would recommend PSPs to their patients (89.5%). They considered such a program a valuable addition to current care (79.7%). The percentage of FDs’ who expected long-term benefits for their workload was relatively low (37.6%).

CONCLUSIONS: In an exploratory survey among German FDs on PSPs, respondents viewed PSPs as a valuable add-on for T2D and CAD patients, while not expecting a positive impact on their workload. Communication with FDs on PSPs may need to highlight anticipated implementation outcomes such as benefits of PSPs to the practice.

ABSTRACT

BACKGROUND: Surgical frailty is a condition in which patients are weak with varied recovery of various organ functions after surgery resulting in unpleasant outcomes. Frailty studies have been conducted in several populations with a limited knowledge on postoperative brain tumor patients. This study aimed to examine factors predicting frailty in brain tumor patients after craniotomy. METHODS: This study was a cross-sectional predictive study. The sample included 85 patients who were 18 years or older and underwent craniotomy with tumor removal from 1 university hospital in Bangkok, Thailand, between February and October 2021. Data were analyzed using descriptive statistic, Pearson correlation, and multiple linear regression, which determined significance level at .05. RESULTS: The prevalence of frailty among participants was 50.6%. Postoperative symptom and mood state were positively associated with frailty (r = 0.410 and r = 0.448, respectively; P < .01). Postoperative symptom, mood state, age, tumor type, and income could explain the variance of frailty in brain tumor patients after craniotomy by 40.3% (R2 = 0.403, P < .01). CONCLUSION: Healthcare providers should plan for discharge planning including assessment and develop the intervention for managing postoperative symptoms and psychological symptoms to promote recovery from frailty that generally occurs after brain tumor surgery.

ABSTRACT

RATIONALE: Pulmonary exacerbation (PEx) events contribute to lung function decline in people with cystic fibrosis (CF). CF Foundation PEx guidelines note a short course of systemic corticosteroids may offer benefit without contributing to long-term adverse effects. However, insufficient evidence exists to recommend systemic corticosteroids for PEx treatment.

OBJECTIVES: To determine if systemic corticosteroids for the treatment of in-hospital pediatric PEx is associated with improved clinical outcomes compared to treatment without systemic corticosteroids.

METHODS: Retrospective cohort study using the CF Foundation Patient Registry-Pediatric Health Information System linked database. People with CF were included if hospitalized for a PEx between 2006-2018 and were 6-21 years of age. Time to next PEx was assessed by Cox proportional hazards regression. Lung function outcomes were assessed by linear mixed effect modeling and generalized estimating equations. To address confounding by indication, inverse probability treatment weighing was used.

RESULTS: 3,471 people with CF contributed 9,787 PEx for analysis. Systemic corticosteroids were used in 15% of all PEx. In our primary analysis, systemic corticosteroids were not associated with better pre- to post-PEx percent predicted forced expiratory volume in 1 second responses (mean difference, -0.36, 95% CI: -1.14, 0.42; p=0.4) or a higher odds of returning to lung function baseline (odds ratio (OR), 0.97, 95% CI: 0.84-1.12; p=0.7), but were associated with a reduced chance of future PEx requiring intravenous antibiotics (hazard ratio (HR), 0.91 (95% CI: 0.85-0.96; p=0.002). When restricting the analysis to one PEx per person, lung function outcomes remained no different among PEx treated with or without systemic corticosteroids, but in contrast to our primary analysis, the use of systemic corticosteroids was no longer associated with a reduced chance of having a future PEx requiring intravenous antibiotics (HR 0.96 (95% CI: 0.86, 1.07; p=0.42).

CONCLUSIONS: Systemic corticosteroid treatment for in-hospital pediatric PEx was not associated with improved lung function outcomes. Prospective trials are needed to better evaluate the risks and benefits of systemic corticosteroid use for PEx treatment in children with CF.

ABSTRACT

The high biomechanical loads in molar region wounds challenge the indication for short implants to be used as a single-unit implant. This study reports on the outcomes of single-unit short implants (≤ 8.0 mm) in the maxillary and mandibular molar regions. Forty-nine short implants were placed in 48 patients to replace a missing molar tooth. Two-piece restorations with screw retention were fabricated. During the follow-up, implant survival and marginal bone loss (MBL) were assessed. The known implant length was used as a reference to calibrate the linear measurements on digital periapical radiographs, and descriptive statistical analysis was performed. The implants were followed over a period of 47 ± 12 months. No implant failure was recorded, and no prosthesis failure was observed. The average MBL was 0.15 ± 0.5 mm. The mean crown height space was 13 ± 3 mm. The overall crown-to-implant ratio was 1.7 ± 0.4. Two technical complications occurred due to the loosening of the unit abutment. After screw re-tightening, no more screw loosening was observed. This study supports the use of short implants as a single-unit implant in the maxillary and mandibular molar regions.

ABSTRACT

The present study evaluated the 2-year changes in soft tissue width after implant placement in healed sites, using two different methodologies to obtain tissue healing: preformed and anatomical abutment caps for customized healing (test) vs conventional healing abutments (control). The null hypothesis was that there would be no difference between the test group and the control group. Patients who suffered from a single-tooth edentulous area in the premolar/molar region were included. Both the standard abutments and the preformed and anatomical abutment caps were immediately screwed on the implants. The final crown restoration was fabricated 3 months later. Primary outcomes (changes in the alveolar soft tissue ridge) and secondary outcomes (testing adverse events and measuring implant/prosthesis survival) were evaluated. Thirty-nine patients (24 women) with a mean age of 57.7 ± 7.1 years (range: 42.6 to 72.8 years) were included. Alveolar widths in both groups showed significant increases from baseline to the 3-month follow-up, with augmentations of 3.6 ± 0.7 mm for the test group and 1.1 ± 0.9 mm for the control group. The gain in soft tissue appeared to be statistically different between the two groups (P < .0001). Contrarily, any subsequent change in width from 3 months to 2 years was negligible and insignificant (< 0.33 mm for both groups). The technique described in the present study encourages the potential for alternative healing based on the guided soft tissue concept, as it either eliminated the need for second-stage surgery or it reduced step-by-step peri-implant soft tissue conditioning, obtaining a tissue contour immediately very similar to that of a final prosthesis.

ABSTRACT

The aim of this systematic review and meta-analysis was to assess whether the addition of enamel matrix derivative (EMD) to a coronally advanced flap (CAF) combined with a connective tissue graft (CTG) resulted in a greater amount of root coverage in patients treated for gingival recessions, as compared to CAF+CTG alone. The search for clinical trials on root coverage procedures comparing CAF+CTG+EDM vs CAF+CTG was completed on online databases and gray literature, and it included studies published up to January 2022. The risk of bias was assessed using the Cochrane bias assessment tool, and the quantitative analysis was performed using a random effects model. A total of 1,917 articles were identified, and 12 underwent full-text review. Three studies were excluded, and 9 were selected for full analysis. The meta-analysis showed that there is a statistically significant difference (P = .04) in favor of CAF+CTG+EMD compared to CAF+CTG alone for the amount of root coverage (mean difference: 0.30 mm; 95% CI: 0.01, 0.58 mm). According to the results of this systematic review and meta-analysis, the addition of EMD to CAF+CTG results in a greater amount of root coverage in teeth treated for gingival recessions.

ABSTRACT

PURPOSE: The importance of consistent outpatient follow-up for management of diabetic eye disease has been well-established. The objective of this study was to identify patient factors associated with being lost to follow-up in post-surgical patients after undergoing pars plana vitrectomy for diabetic eye disease.

METHODS: The charts of diabetic patients undergoing pars plana vitrectomy for non-clearing vitreous hemorrhage at an academic medical center by a single surgeon between 2012 and 2019 were reviewed. The rates of loss to follow-up during the postoperative period were compared based on patient distance from clinic and insurance status.

RESULTS: A total of 144 patients met inclusion criteria. 45 patients (31.25%) were lost to follow-up during the three-month postoperative period. The rate of loss to follow-up increased with every postoperative visit and was significantly higher for patients living greater than 30 miles from clinic versus patients living within 30 miles from clinic. There was no statistically significant difference in loss to follow-up based on insurance status.

CONCLUSIONS: Increased distance from clinic presents a challenge to providing safe and effective post-surgical care to diabetic patients. This presents opportunities for co-management or other creative strategies to improve post-surgical follow-up rates for at-risk patients.
